RE: IIS and Tomcat basic configuration questions
No, Tomcat and IIS can be on different machines (the redirector is on the IIS server, but it is simply a DLL). One of the entries in the properties file used to configure the redirector is the name of the machine where Tomcat is running. This is how the redirector knows where to redirect the request to. -Original Message- From: Brantley Hobbs [mailto:[EMAIL PROTECTED]] Sent: Thursday, January 23, 2003 10:48 AM To: [EMAIL PROTECTED] Subject: IIS and Tomcat basic configuration questions Hello all. I'm new to the entire concept of Tomcat and I have a question which I have not found a clear explanation for. Does Tomcat have to be installed on the webserver? In other words, can I not just install the redirect filter (and not Tomcat, per se) on the webserver and have it connect (using ajpv13) to a back-end Tomcat server? I only want to install the redirect filter on the webserver. Does a working JVM need to be in place for the filter to work properly?

[OT] Charting Libraries
I am looking into the ability to add charting capabilities to our intranet app and was wondering if anyone else has experience with any of the available packages. One of the requirements is, of course, that I can create the graphs in Tomcat and send the results to a browser, and I would prefer something open source. This has narrowed my choices to jChart or JFreeChart. Has anyone worked with either of these? Also, does anyone know of any I may have missed?

Your best bet would be the Oracle web site (otn.oracle.com). The only thing
that uses DLLs is Windows, so that won't apply to HP-UX or Linux.

Subject: RE: HP-UX 10.20 + Oracle
Hi I am offsite today, so not sure if this will work, anyway.
I have tried setting LD_LIBRARY_PATH but it still does not work.
I suspect that I have conflicting versions or classes, so my questions
are:
1. Where should I get classes12 or classes111 from for HPUX 10.2 and
Oracle 8.0.4
(the ones I am using are copied from Linux)
2. I have seen mentioned that an associated DLL is required, which one?
and where
should it go?
Thanks once again
John
Make sure you have the LD_LIBRARY_PATH environment variable set to
$ORACLE_HOME/lib (I think :-\ ) At least you have to on Linux.

RE: Easy question - Java Beans
If I may jump in...I like to use the Iterator pattern for building select
lists. While this may not be the best application for a situation where the
list of values is predetermined (such as with states), it works well when
reading from a variable list of values such as from a database.
In my bean I keep the list of values along with an index of the last one
retrieved. My JSP code then contains something like:
% while (pageBean.hasMoreStates()) { %
option value=%= pageBean.getStateAbbv() %%= pageBean.getStateName()
%/option
% } %
Each call to hasMoreStates increments the counter and returns true if there
are still more in the list. The calls to getStateAbbv and getStateName use
this counter to get the proper value from the list (usually a property of
another object held within an ArrayList). Also, make sure you enclose
everything within the loop in curly braces.
If I need to pre-select a specific option, I add another call which returns
the string selected or an empty string, depending on if the iterator is
currently on the proper entry.
% while (pageBean.hasMoreStates()) { %
option value=%= pageBean.getStateAbbv() % %=
pageBean.getStateSelected() %%= pageBean.getStateName() %/option
% } %

How would your original select look for the states?
I have a variable in the bean for state which is the value (i.e. NY) but
not one for the state name (i.e. New York). My select is basic:
select name=state
option value=NYNew York/option
/select
In my bean I have private String state; with the getter and setter methods.

Denise,
Start with your basic select tag, and then in your code that emits the
list of option tags, do something like this:
option value=' + stateCode + ' + ((stateCode.equals(currentStateCode))
? selected : ) + + stateName + /option
In other words, emit the
option value='NY'New York/option
tag, or the
option value='NY' selectedNew York/option
variant, depending upon whether the option you are about to emit is the
currently selected option.

RE: byte serving PDFs
There is really nothing special about serving a PDF document other than setting the correct MIME type. If you are using Tomcat to serve static PDF files, just make sure the file extension is .PDF and the browser should recognize it properly. If you are dynamically generating the PDF and sending it back as a byte stream, just set the Content Type header to application/pdf and send the data back through the output stream. You will have to do this with a servlet as a JSP page tries to treat everything as text. -Original Message- From: Elizabeth Fisher [mailto:[EMAIL PROTECTED]] Sent: Friday, December 13, 2002 1:01 PM To: Tomcat Users List Subject: byte serving PDFs Does Tomcat support byte serving of PDFs? -Elizabeth -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

I posted this question a few days ago, but didn't get any responses. Maybe I did something wrong. So I re-posted this question. Symptom: I have a Tomcat application, running with Apache (1.3.26) and Tomcat (3.3) in W2k with sp3. I experienced Tomcat died several times (freq: once a week), while Apache remained running. Question 1: Where I can capture the last exception or other error messages before Tomcat died? I need to find out what caused Tomcat to die first, before I can take steps to fix the problem. Does any one experience similar situation? When I said Tomcat died, I mean: In W2k service mode, it simply stopped. In non-service mode and in the same command window, a prompt was displayed and no more log4j messages on display. The application did generate Log4j messages in log files at ~\tomcat\logs. I cannot find any Exceptions at end of file. Any suggestions are welcome. thx in advance.

RE: Tomcat Scalability - Long
We have a similar hardware setup (PIII 1GHz 512M) but running Tomcat 4.0.4 on Win2k/IIS and accessing a DB2 database on a separate iSeries server. The system is used by our sales reps in the US and Canada (about 30) over a VPN, so it can see activity at any time. It never really gets hammered but traffic seems to come in spurts with the highest load I have seen of about 5 simultaneous users and the longest session (although we don't use session objects) of about 45 minutes. Keep in mind that I have never actually monitored the traffic, just made mental notes as I was reviewing the log files. So far the only time we have had to restart the machine is to install another MS security patch. The longest continual uptime has been a little over 19 days (the server has only been in production about 10 weeks) and the memory used by Tomcat seems to hover right around 24M. Response time is always in the sub second range, except for a few database queries that seem to take a little longer (still need to do some SQL tuning). I don't know if you can call this solid information, but so far I have not seen anything to worry about scalability wise. -Original Message- From: Brandon Cruz [mailto:bcruz;norvax.com] Sent: Thursday, October 24, 2002 3:36 PM To: Tomcat Users List Subject: Tomcat Scalability - Long Does anyone have any solid information about the scalability of Tomcat? It seems very limiting to me, but that is hopefully due to improper configuration. Here is our situation and what seems to be happening under a small amount of stress. ---About our Environment--- PIII 1.0Ghz 512 Meg Ram Linux RedHat 7.1 MySQL Database Apache 1.3.x mod_jk - logging turned all the way down Tomcat 3.2.4 - contexts *are* reloadable right now SUN JDK 1.3.1_01 ---About our Application--- Our Application is a content management tool that reads and writes to the MySQL Database and reads and writes files. All the pages within this application are served by Tomcat 3.2.4. About 80-120 people per day log into this application and spend anywhere from 10 minutes to one hour working on the application. At any given time there are between 15 and 50 active database connections. ---What we are seeing--- Tomcat needs to be restarted every few days. If we don't restart it, it seems tomcat eventually locks up and does not respond at all. No errors or anything are reported, it just will not respond. Apache continues to work during this time and all static HTML pages are accessible. CPU - The processor usage seems to slowly increase as time goes on. After about one day, it seems one java process uses 30% of available CPU or more, depending on whether users are performing operations or not. When nobody is doing anything, the processer still seems to be sitting around 30% until tomcat is restarted. This seems to cap after three to five days and not increase too much more. RAM - This slowly increases and never stops increasing. We do not have any special parameters set for the VM when it starts, but this does not seem to matter. The RAM gets up to about 135 MB after four or five days, but would continue to grow if tomcat were not allowed. Can anyone explain this behavior, talk about the scalability of Tomcat, or provide any similar working solutions that perform better than this? Is it normal, should we just throw more hardware at it? Are there configuration parameters that can be used to increase performance, such as set reloadable=false in all contexts? Would we get better performance if we upgraded to 4.x, or would that just be more work for little improvement? -- To unsubscribe, e-mail: mailto:tomcat-user-unsubscribe;jakarta.apache.org For additional commands, e-mail: mailto:tomcat-user-help;jakarta.apache.org -- To unsubscribe, e-mail: mailto:tomcat-user-unsubscribe;jakarta.apache.org For additional commands, e-mail: mailto:tomcat-user-help;jakarta.apache.org

I hope it saves someone a little time troubleshooting. _Situation_: Attempting to run tomcat 4.0.4 as a service on NT4.0 SP6 using jk_nt_service.exe. May apply to other versions of Tomcat and Windows as well. _Symptoms_: Command jk_nt_service -i tomcat -a wrappers.properties adds the service just fine, but attempting to start the service with command jk_nt_service -s tomcat or from NT Services panel fails. _Most Likely Cause_ (Of course you may have other problems that I don't know about, but this one will definitely hang you up): Spaces in your path definitions. For example, I originally had the setting: wrapper.tomcat_home=d:\Program Files\Apache Tomcat 4.0 Quoting the path with double or single quotes will not rectify the problem either. _Workaround_: Use Dir -X to find the short (DOS 8.3) names of your directories and use those instead. For example, my new path setting is: wrapper.tomcat_home=d:\PROGRA~1\APACHE~1.0 This will eliminate the spaces and the service will start happily.

RE: Simple WAR files
Personal preference I suppose. I, personally, almost gave up trying to teach myself Java using the notepad/javac/System.out.println routine. Once I was able to step through the code in the debugger (and get something to actually work) I started to appreciate Java. I guess I need that instant gratification. ;o) I would hate to guess how long it would have taken me to get my first servlet to work using the manual method.

RE: OFF-TOPIC: Pointers to CallableStatement docs?
When you say it returns a status, do you mean it is a function (I work
primarily with Oracle, so if this does not apply to MS I apologize)?
If so, you need to make the call something like:
CallableStatement stmt = conn.prepareCall({call ? = proc(?,?, ... )});

Subject: OFF-TOPIC: Pointers to CallableStatement docs?
Hello -
I think there is a java-user list, or even a jdbc-interest list, but I'd
rather not subscribe when all I need is one quick pointer, so I am hoping
someone on this list can get me started.
I'm having quite a bit of difficulty working with stored procedures in my
classes and servlets. The database is MS SQL Server 2000. I've read every
single doc I can find, both at Sun, through Google, and even through the
driver vendor's documentation. I even scammed some code from a JDBC 3.0
book (the only one I could find) at Border's, with still no luck.
Can anyone point me to a resource that explains how to setup stored
procedures in a CallableStatement correctly? I understand about registering
the output parameters and setting the input types, and I understand that the
parameters in a CallableStatement are numbered from left to right starting
at 1. I've seen the examples at Sun, etc. but they're not much help.
The problem is that all of the examples I can find deal with very simple,
very rudimentary stored procedures, like finding the average of two numbers,
or whatever. Our stored procedures are more involved than that.
Example: a stored procedure used to validate logins. It has 5 input
parameters, and 5 output parameters. It returns a status. According to the
docs I have read so far, that means I should have a CallableStatement with
11 question marks (?) in it (5 + 5 + 1 = 11). but that doesn't work, and
I have tried every combination of inputs, outputs, input/outputs, etc. that
I can think of, to no avail.
Any help or pointers to resources that explain stored procedures and
CallableStatements in more in-depth fashion would be greatly appreciated.

RE: OFF-TOPIC: Pointers to CallableStatement docs?
I don't know if it is possible in your case, but have you tried changing the
parameter types within the stored procedure to something simple, like all
strings? I always just try to get SOMETHING to work, then go from there.
;o)
I think I recall Oracle having problems with booleans a while back so I
reverted to integers (1 and 0). Maybe this is actually a JDBC thing, in
which case you may be experiencing the same issue.
From the little bit of DB/2 work I have done I know IBM's error messages
will lead you to believe the number of parameters do not match, when in fact
the problem is the parameter types. Again, just something to test.

Right. My setup looks like this:
cstmt = sConn.prepareCall({? = call
sp_validate_pwd(?,?,?,?,?,?,?,?,?,?)});
Basically, there are 5 inputs (username, password, IP address, browser type,
and referer) and I'm supposed to get a return status back (bad or good) and
5 outputs: 3 booleans and 2 strings (isValid, isExceeded, isEnabled, name,
and title).
I've tried everything I can think of...only having 6 question marks, having
all 11, only using 5, etc. to no avail. I enabled debug logging on the
driver, and I get messages that say parameter my_parameter not registers as
output or not registered as input, even when they are, and regardless of
how I use the set*() and registerOutParameter() methods. Very confusing.
I'd love to find a complete stored procedures How-To somewhere that
addresses complex stored procedures instead of the basic tutorials that do
simple math or just insert a row.
Thanks for the reply.

The default registry entries have a typo.

RE: Yet Another IIS/Tomcat Problem
I found the problem and it appears to be a bug, or at least a default configuration/documentation problem. I followed the AJP Connector documentation (at http://jakarta.apache.org/tomcat/tomcat-4.0-doc/config/ajp.html) to have Tomcat create the iis_redirect.reg file but it seems the entry created for extension_uri does not match the actual name of the dll (downloaded from http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/v4.0.3/bin/win32 /). The name added to the registry is isapi_redirect.dll but the name of the file is isapi_redirector.dll. There also seems to be confusion about the worker.properties file. The AJP Connector documentation refers to the file as worker.properties but the entry created for worker_file in iis_redirect.reg is workers.properties. The Tomcat IIS How-To (at http://jakarta.apache.org/tomcat/tomcat-3.3-doc/tomcat-iis-howto.html, outdated but there doesn't appear to be one for 4.0) refers to this file as workers.properties. I realize (now) that the name of the file does not matter as long as the registry entry is correct, but this confusion certainly does not help. Finally, and one I have yet to figure out, there is also conflicting information about the names of a couple of entries within the worker(s).properties file. In the Tomcat Worker How-To (at http://jakarta.apache.org/tomcat/tomcat-3.3-doc/Tomcat-Workers-HowTo.html, again outdated but the only one I could find) it refers to workers.tomcat_home and workers.java_home. But the AJP Connector documentation calls these worker.tomcat_home and worker.java_home. As I said, I have yet to figure out which of these is correct as it doesn't seem to matter what I use. It seems to work either way. As far as I can tell they are both wrong or the entries are ignored entirely.

Are you sure you really want independent instances of the bean, or just
the
ability to keep the variable values separate by user? If it is the
latter,
then just use local variables in your bean methods.
It seems that couldn't work. The value of such variables can be updated by
another user's when there are two or more users calling the same java bean
almost at the same time. Here is my main work. First jsp write uname (when a
user login the website, there is a user name uname) to the bean and
activate it, and get the result or save it to the database.
Jsp file:
jsp:useBean id=mb class=mybean.test scope=page /
???How about the scope value? session or request or page?
jsp:setProperty name=mb property=uname value=%=loginname) %/
pThe result is:
%= mb.test() %/p
Bean code:
public class test
{
String uname= ;
public synchronized int test()
{
int real=0;
int eventCounter=0;
int numEvents;
// connect to the database and get the numEvents according to the
uname.
.;
while(eventCounter=numEvents)
{
real=eventCounter;
// wait for 0.01 second
try{wait(10);}
catch(InterruptedException e){};
eventCounter++;
}
return real;
}
public synchronized void setUname(String sec)
{
uname= sec;
}
}
For user1, numEvents=100; and user2, it's 120. So I want to run them at the
same time, and hope to get resuls 100 and 120 respectively. But in fact I
got both 100 or 120. Have any idea? If my description is not clear, tell me
please.

Subject: Urgent Re: Newbie: Servlet under Windows does not run
I am really desperate. I need to be able to demonstrate this servlet by
Tuesday evening and Tomcat still refuses to run it.
Essentially all that I have done is copy the examples from a book and change
the names to protect the innocent. The first few lines of the .java file
are:
package Census;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.sql.*;
public class CensusQuery extends HttpServlet {
I then compile this class and create the .war file with the following .bat
file:
set PATH=C:\jdk1.3.1\bin;%PATH%
set
CP=D:\jakarta-tomcat-3.3a\lib\common\servlet.jar;WEB-INF\classes;%CLASSPATH%
javac -d WEB-INF/classes -classpath %CP% CensusQuery.java | more
jar cf Census.war *.html WEB-INF
When the .war file is deployed by Tomcat the class file is located at:
D:\jakarta-tomcat-4.0.3\webapps\Census\WEB-INF\classes\Census\CensusQuery.cl
ass
All of this looks completely according to the documentation I have read.
What am I doing wrong so that Tomcat cannot find the class?

RE: Urgent Re: Newbie: Servlet under Windows does not run
Are you absolutely sure the problem is with CensusQuery and not a referenced
class? It could be that Tomcat can't find another class that is referenced
by CensusQuery, so it cannot load CensusQuery
Try stripping (or commenting) out all of the code except for a println call.
This will show you if the servlet is actually being located or not.

What URL are you using to get to the servlet?
I have tried a very wide range of URLs. According to all of the
documentation the one that should work is
http://localhost/servlet/Census.CensusQuery That is using the class name.
However when that failed I also tried /servlet/Census/CensusQuery,
and /servlet/CensusQuery. Since in my web.xml file, which I posted
earlier, the name of the servlet, as opposed to the class, was Census1901 I
also tried /servlet/Census1901. I have also tried using URL mapping
specified in the
WEB-INF/web.xml file. In any event the bottom lime is that when I request
the above URL TomCat does go looking for my class. It just can't seem to
find it!
I know that I must be doing something wrong, because nobody else seems to be
having any difficulty running servlets, but this is driving me crazy. I
have been trying everything I can think of for more than a week and TomCat
keeps claiming that it can't find the class. I have read the documentation
over and over again. I have gone with a fine tooth comb through the
examples trying to see what they are doing that is different from what I am
doing. I just don't understand why this is so bloody difficulty.
Just to put every bit of the documentation of this problem in one place:

RE: How can I resolve this IllegalStateException: Response has a lrea dy been committed problem?
Is it possible to change the Create servlet to a simple class that accepts the request as a parameter? Since it does not manipulate the response object, there is no need to pass it. Also, you can then call Create using a regular method invocation, rather than using forward. It may require some work, but you could eliminate the double forward issue. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Friday, March 08, 2002 8:45 AM To: [EMAIL PROTECTED] Subject: RE: How can I resolve this IllegalStateException: Response has a lrea dy been committed problem? The exception seems to be occurring because the Home servlet forwards more than once (to different locations) - first to home.jsp, then later to the Create servlet. It is definitely the fact that it is forwarding to more than one place, that is causing the problem. I know this because if I call the Login servlet and fail the login authorization - this servlet consequently forwards to login.jsp more than once (first - to display the fresh login page, and second - to prompt user to try again). This however does not give me an exception. Given that my Home servlet is like the central servlet, it needs to be capable of forwarding to a variety of places, depending on the activity selected by the user. Ryan - I have looked at create.jsp and, as far as my little mind can see, it does not play with the response object at all. All it does is get a few session attributes and fit them into the page using %= blablabla %. Could that be a problem? This problem is not isolated to the Create example. There are other activities the user can choose which all follow exactly the same forwarding mechanism (except to different servlets), and these give exactly the same exception.

RE: How can I resolve this IllegalStateException: Response has a lrea dy been committed problem?
You don't need to forward back to the original servlet. Each call is done as a stack, so when the JSP returns, control comes back to the Create servlet. When the Create servlet returns, control comes back to the Home servlet. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Friday, March 08, 2002 9:27 AM To: [EMAIL PROTECTED] Subject: RE: How can I resolve this IllegalStateException: Response has a lrea dy been committed problem? Yep that's right. Only one forward getting done per request. The main controller servlet (e.g. Home) forwards to another more specific controller servlet (e.g. Create), which then forwards to a JSP. Then later, that servlet forwards back (?? Maybe this isn't wise?) to the main controller servlet. A whole lot of forwarding going on. -Original Message- From: Ryan Daigle [mailto:[EMAIL PROTECTED]] Sent: 08 March 2002 13:56 To: 'Tomcat Users List' Subject:RE: How can I resolve this IllegalStateException: Response has a lrea dy been committed problem?

Actually, the way forward works came as a surprise to me as well.

RE: How can I resolve this IllegalStateException: Response has a lrea dy been committed problem?
Because the Home servlet holds an object reference to the session, it acts as a pointer to the actual object data. If another servlet obtains a pointer to the same object and modifies the data, the changes will be reflected in the first servlet without having to re-get the reference. However, as a precaution I don't like to hold object references between calls like this.

OK. I never knew the forward call actually returned - ever. I will experiment with this. I'm nearly ready to go away and stop pestering you all, but one more question... Say the Home servlet gets the session object from the request. It later forwards the request to the Create servlet, which essentially modifies the session. Then, when the forward call returns, will the Home servlet's session object be the old one or the updated one? Or will it have to do request.getSession() all over again in order to get latest session.

RE: client side object to server side
I have been developing an app that needs to send large amounts (~kilobytes) of structured data between the server and the client. I have been working on a framework to facilitate this by using JavaScript's object notation. Essentially, I have a JavaScript function that converts a JavaScript object or array into it's string representation. This string is then placed in a hidden field and posted to the servlet. The servlet then reads the field and decomposes the string into an object hierarchy composed of strings, floats and Booleans either singularly (addressable by name) or in an array. The client-side is very small. It consists of a single JavaScript function that creates the string. The servlet-side piece requires several class files which I have placed in a package. At this time there is very little (read: no) documentation and it is probably not the most efficient code, but for the most part it works. The only known current limitation is the inability to handle nulls. Please keep in mind that for small amounts of data, this would be overkill. By the time you define the structure of the objects being passed you could have written and debugged the code to add a dozen or so hidden fields and process them in the servlet. But in my case I need to pass an object that contains multiple, variable-length arrays, some containing another object. Trying to do this by adding hidden fields through the DOM was getting ugly, so I came up with this. If you or anyone else is interested I could post both the client and server side code, but I would need to tie up a few loose ends before subjecting myself to a code review. :0) I also need to write up a page or two of documentation (something I need to do anyway), so it may take a day or two.

RE: Invoking a process on the server from a servlet
The problem is due to NT (or 2000) not allowing the Tomcat service to
interact with the desktop. If you bring up Task Manager, you will probably
see your invoked process running, but it can't create window. In fact, the
only way you will now be able to get rid of it will be to kill it in Task
Manager.
I don't know of any way around this.

Subject: Invoking a process on the server from a servlet
I have the following code in my servlet, where 'out' is the
HttpServletResponse object.
Runtime t = Runtime.getRuntime();
try {
Process proc = t.exec( c:\\TaskInfo.exe );
out.write( invoked );
} catch ( java.io.IOException ioe ) {
out.write( ioe.toString() );
}
What I'm getting is invoked in the browser window, but nothing visibly
happens on my local machine( ie. server). I was hoping TaskInfo would start
up. What I really want to do is open a file in notepad to tell me a visitor
has just arrived. Am I barking up the wrong tree altogether. Should I
generate an event and listen for it in another app running as a listener in
the background, or is there just no way of invoking a process on localhost
from a servlet.
Thanks.
If this is the wrong place to be asking these questions, please let me know.

RE: Invoking a process on the server from a servlet
If you want the messages to appear real-time, I think the previous suggestion to send a TCP message to a waiting listener app would be you best bet. This app could just sit there with an open window that scrolls any messages that it receives. -Original Message- From: Stephen Clarke [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 22, 2002 11:08 AM To: Tomcat Users List Subject: Re: Invoking a process on the server from a servlet - Original Message - From: Wagoner, Mark [EMAIL PROTECTED] To: 'Tomcat Users List' [EMAIL PROTECTED] Sent: Tuesday, January 22, 2002 3:45 PM Subject: RE: Invoking a process on the server from a servlet The problem is due to NT (or 2000) not allowing the Tomcat service to interact with the desktop.

JSP Won't Compile Under Tomcat 4
I am trying to move an app from Tomcat 3.3 to 4.01 and am running into a really strange problem. Everything works fine except for my error page, which won't compile. I get the following: 2002-01-18 09:08:18 ApplicationDispatcher[] Servlet.service() for servlet jsp threw exception org.apache.jasper.JasperException: Unable to compile class for JSP An error occurred at line: 18 in the jsp file: /error.jsp Generated servlet error: D:\Tomcat\work\localhost\_\error$jsp.java:64: Class org.apache.jsp.PrintWriter not found. exception.printStackTrace(new PrintWriter(out)); ^ 1 error I just installed Tomcat on the Windows NT box and selected all the options except for the source code. Tomcat 3.3 is on the same box and, as I said, it works fine under that. Is there some classpath setting I have to make?

RE: JSP Won't Compile Under Tomcat 4
I'm not importing it because I am not using directly. Tomcat is throwing the error when it is invoking its internal JSP compiler. To be honest, I don't even know which JAR file the org.apache.jsp package is in. -Original Message- From: Justin Rowles [mailto:[EMAIL PROTECTED]] Sent: Friday, January 18, 2002 9:17 AM To: 'Tomcat Users List' Subject: RE: JSP Won't Compile Under Tomcat 4 An error occurred at line: 18 in the jsp file: /error.jsp Generated servlet error: D:\Tomcat\work\localhost\_\error$jsp.java:64: Class org.apache.jsp.PrintWriter not found. exception.printStackTrace(new PrintWriter(out)); ^ 1 error Is PrintWriter found in the org.apache.jsp package?

RE: JSP Won't Compile Under Tomcat 4
Well, that helped. Although just importing the package wasn't enough. I had to change the scriptlet in the JSP to specifically say java.io.PrintWriter. Now I am getting an IllegalStateException, but at least one hurdle is over. I still can't understand why none of this was necessary under Tomcat 3. -Original Message- From: Justin Rowles [mailto:[EMAIL PROTECTED]] Sent: Friday, January 18, 2002 9:32 AM To: 'Tomcat Users List' Subject: RE: JSP Won't Compile Under Tomcat 4 I'm not importing it because I am not using directly. Tomcat is throwing the error when it is invoking its internal JSP compiler. Hmm... interesting. Yes, Tomcat is throwing the error when it tries to compile the .java file that it has genereated. There is, however, a source file called error.jsp from which it has generated the .java file, and this presumably references PrintWriter without importing its class from its package. To be honest, I don't even know which JAR file the org.apache.jsp package is in. But that was my point - PrintWriter is *not* found in the jsp package, it's found in the java.io package so if you want to use PrintWriter you must import java.io.PrintWriter or java.io.*. Hope that helps, Justin. -- You're only jealous cos the little penguins are talking to me. *** For more information on Ordnance Survey products and services, visit our web site at http://www.ordnancesurvey.co.uk *** -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED] -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]
RE: Session Tracking throughout apps
Unfortunately, I think the answer to your question is it depends. You could code the controller servlet to handle all of the requests, in which case you would want to make it as small and fast as possible. Possibly get the session info, request a login if there is no session (if that is a requirement) determine the next servlet and pass on the request. You can also have different servlets for each of your request types (message board, etc.) and, as long as they are all in the same context, they will have access to the same session information. The mappings for these would go in the application's web.xml file rather than the server.xml file. There would be one context entry in server.xml which contains all of the different servlet mappings. If your apps are really totally unrelated other than sharing session info, the multiple servlet mappings may be the most flexible. If there is a good deal of processing that has to be performed with each request regardless of the target servlet (such as getting a JDBC connection) then the single controller is probably better. -Original Message- From: Charles N. Harvey III [mailto:[EMAIL PROTECTED]] Sent: Friday, January 18, 2002 2:47 PM To: Tomcat Users List Subject: Session Tracking throughout apps Hello list. I'm not sure if this is a tomcat question or a java (servlet) question so try not to get too angry if this is on the wrong board. I am setting up my environment to use a controller servlet that brokers all the requests that come in for the site. About 80% of my site are pages that will be served up this way, through the controller. But the other 20% are seperate applications - message boards, photo uploads, contests with registration. What I am slightly confused about is, should the requests for these apps also go through the controller servlet? And if so I don't know how yet - but I will find out. If not (which is my current level of knowledge) then each one gets its own mapping in server.xml and its own directory structure. If this is the case, how do I maintain session across the rest of the site and these side apps? I am pretty new to java hence my confusion. Can I just pass the session object from one to the other? Is there something special I have to implement? Any help would be greatly appreciated. And if this post is in the wrong place just say so and I will find the appropriate java list to post to. Thanks.
